arvan_list_page_rules

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description adds no behavioral information beyond the annotations. Annotations already declare readOnlyHint and destructiveHint. The description does not disclose pagination, performance, error handling, or any side effects. No value is added over structured metadata.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence that front-loads the purpose. There is no wasted text. However, it is so brief that it lacks detail; a second sentence providing context would be beneficial but does not detract from conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple list tool with one parameter and no output schema, the description minimally communicates the main action. However, it does not describe the return value or any prerequisites. Given the existing annotations, it is adequate but not complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has 0% description coverage for the 'domain' parameter. The description merely restates that it lists for a domain, but does not explain the expected format, examples, or constraints of the domain parameter. With low schema coverage, the description should compensate but does not.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (list) and resource (page rules) and scopes it to a domain. It distinguishes from sibling tools like arvan_list_dns_records. However, it does not add any nuance about what page rules are or how they are listed.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool vs alternatives. It does not mention that it is a read-only operation (though annotations indicate readOnlyHint) or that the domain must exist. A user might not know when to prefer this over other list tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
